摘　　要：黄土为兴电灌区最主要地基岩性之一。通过资料收集与现场勘察,对灌区黄土所属地貌、时代成因、分布规律进行总结,以室内外试验资料为基础,对黄土的物理特性、力学特性及湿陷特性等方面进行了分析、研究,总结出不同时代黄土工程地质特性的差异,得出灌区更-全新世黄土的湿陷性变化规律;并针对不同时代、不同成因的黄土提出了差异性工程处理措施建议。Loess is one of the most important foundation lithology in Xingdian Irrigation Area.Through site investigation and data collection,the geomorphology,genesis and distribution of loess in irrigated area are summarized.Based on data from indoor and outdoor tests,the physical,mechanical and collapsible properties of loess are studied and analyzed.On that basis,the differences of engineering geological characteristics of loess in different ages and variation of collapsible loess in irrigated areas are summarized.In addition,different engineering treatment measures were proposed for loess of different eras and different genesis.
